I completely agree with that, but you're not going to solve that problem by tearing down all the single family homes that exist in our current cities. Many of the people who get priced out of their homes will just move to the suburbs and small towns and balloon them further.

Yes we can afford and need to densify around existing infrastructure, to some extent, but we also desperately and urgently need to start building transit infrastructure in small towns and connecting them to our big cities so that we can have a region of mid sized cities, all capable of supporting a walkable lifestyle. Just densifying around existing transit without investing in building new regions is a race to the bottom that will benefit the rich landlords that lease those buildings back to us.
